Set up the tangent plane along lock body length direction, cup joint anticreep gasket and lock body, anticreep gasket inner circle shape is unanimous with the cross-section of lock body end, makes the anticreep gasket can not be rotary motion around the lock body, buckles the spacing claw of anticreep gasket, and lock nut edge is withheld to spacing claw, even screw thread damage or pretightning force decline to even make lock nut, also can not become flexible to guarantee that the lock body can not follow the door plant and drop.

Preferably, the peripheral surface of the lock body is provided with two symmetrical tangent planes along the length direction of the lock body.

Preferably, the periphery of the anti-falling gasket is provided with two limiting claws.

Compared with the prior art, the utility model, have following advantage:

utilize the tangent plane structure of lock body and the spacing claw of anticreep gasket, with lock nut's rigidity, no matter long-time twisting moves, still the screw thread of nut takes place wearing and tearing, corrosion, can not make the pretightning force of nut reduce, has effectively avoided not hard up of whole lock to drop even, has prolonged the life of lock.
